If you receive no error’s at all then try to run the Update again, if it fails then continue reading on the next page.

6. Run a Malware Scan

A reason Windows Update might not be working can be a Malware Infection, let’s take a look and see it that is the case.

1. Download MalwareBytes from the orginal website

2. Install the malwarebytes and then, if it asks, update the program.

3. After the program is installed and updated if necessary, run a scan by clicking on Scan Now

4. Wait for the scan to complete, depending on your system it’s performance this can take several minutes to hours.

5. Remove the infections from your system by following the steps given by MalwareBytes and then reboot your system.

Reboot your device and look if Windows Update is now working, if it’s not then continue to the next page.

7. Refreshing your system

If the problem stills persist, then there is currently no known fix for this problem, many people could execute the update successfully after refreshing their system and then trying to apply the update again, if you wish to try that then read:

    Thank you. This fix my problem even thought I wasn’t getting any error messages. Just “Windows could not complete updates. Restoring to previous settings.” After trying steps 1-3 of your troubleshooting article and those didn’t change anything, although step 4 was the solution. When it came to the step for stopping the msiserver is said it wasn’t started. When it was time to start the msiserver the response was that msiserver was not responding to conrtol. So I rebooted and went back to cmd prompt for admin and tried starting the msiserver. This time it started and then I went back to check for updates. It found 34 important updates which I proceeded to allow windows to install. This time all went well and now my HP ENVY dv6 is now up to date and hopefully no more problems like this.
